Hey guys,

Im new here but i have a 2013 f150 with the 5.0. It has has a tap since new but hasnt gotten any worse and the dealer said it was normal. Recently it was about 5 below Fahrenheit and the truck hadnt been running in 3 days. I started it and it instantly started banging with a healthy puff of blue smoke. Any ideas? Has 8000 kms since last oil change at the dealer. Has 102k kms on it so just out of warranty.

Thanks everyone,
Brad

 

blue smoke is oil. Makes me wonder about the pistons.....some 5.0s have had problems.....

 

This is the second time it has done it like this. Most days it starts fine with no smoke at all. To me its like a valve lifter is stuck or something. It was rattling pretty good. I have remote start and it was loud enough i heard it from inside the house, looked outside and there was a nice puff of blue. My 2011 had the excess oil consumption problem which this truck does not suffer from. Weird

 

Would full synthetic 0w20 help in the cold canadian winter? Its running 5w20 semi syn from the dealer at the moment and always has since bought new

 

I don't know. but if you could hear it in the house, sure sounds like internal problems to me.

 

I wonder if you can get an extended warranty? I may cost you $1,500; but better to spend that and get coverage on the whole truck than spend more than that just on the engine.

 

Blue smoke on startup is usually the valve guide seals beginning to wear out. I haven't heard of the modern Ford V8 engines being prone to this though. Using a 0W20 oil will help reduce wear upon startup, but if you've already got oil getting past piston rings or valve guide seals, that grade of oil may exacerbate those issues.

 

Hi Brad,

That engine shouldn't be banging or having blue exhaust smoke. Send me a PM with your VIN, full name, phone number, and servicing dealer info. I'll see what resources are available to help,
